Robot Cleaner Coordination Using Shared Cleaning Path Information
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Robot cleaners operate inefficiently due to overlapping cleaning areas with user-operated cleaners and lack of synchronization in cleaning methods, leading to reduced user satisfaction.
Innovation Solution
A robot cleaner that shares cleaning area information with user-operated cleaners, uses a neural network model to determine location based on communication signal strength, and generates a cleaning plan based on record information from both cleaners to optimize cleaning operations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If a robot cleaner operates autonomously in the same space as a user-operated cleaner, then cleaning coverage increases, but cleaning efficiency decreases due to overlapping cleaning areas
Solution Approach 1:
The patent merges the operations of multiple cleaners (robot cleaner and user-operated cleaner) by enabling them to share cleaning area information through communication. The robot cleaner receives cleaning area data from the user-operated cleaner and adjusts its cleaning path to avoid overlapping, thereby combining their efforts to cover more area without redundant cleaning.
Solution Approach 2:
The system implements feedback by having the robot cleaner continuously receive cleaning area information from the user-operated cleaner and adjust its cleaning plan accordingly. This real-time information exchange allows the robot cleaner to modify its behavior based on the current cleaning status, optimizing overall cleaning efficiency.
2Device complexity
If the robot cleaner operates independently without sharing information, then device complexity is reduced, but user satisfaction decreases due to redundant cleaning
Solution Approach 1:
The robot cleaner is designed with multi-functionality, capable of operating both independently and in coordination with a user-operated cleaner. It can function as a standalone cleaning device while also serving as a collaborative partner that receives and processes cleaning area information from external cleaners, adapting its behavior to maximize user satisfaction.
3Productivity
If the robot cleaner uses cleaning record information from external cleaners, then cleaning efficiency improves, but information processing complexity increases
Solution Approach 1:
The patent extracts only the essential cleaning area information from the user-operated cleaner's data, rather than processing complete cleaning records. The robot cleaner receives and utilizes specific cleaning path and area data to adjust its own cleaning plan, minimizing information processing complexity while maintaining improved cleaning efficiency.
